8 Claims.

This invention relates to books and-more particularly to bindings, such for example, as those for holding together stacks of separate sheets of paper and the like.

An object of, my invention is to provide a multipiece binder ring whose pieces are completely separable and, when connected, and linked through a binding hole is capable of unlimited turning in the hole.

Another object is to provied binding means adapted to be supported by and capable of expeditious attachment to and removal from leaves or other material adapted to be bound thereby.

A further object isto provide a book assembly including a binder which binds a'staek of. sheets in such manner as to allow the top'and bottom sheets to be flat, back to back.

A still further object is 'toprovide binding means adapted to bear initials or other indicia.

Further objects and advantages of the invention will appear as the description proceeds.

Various forms of the invention are illustrated on the accompanying drawing, in which:

Fig. 1 is a fragmentary isometric view of a book assembly embodying my invention. 7 Fig.2 is an elevation of a binder appearing in Fig. 1.

Figs. 3- and 4 are similar to 1 but show two other forms. v I

and 6 but with the ends of the split ring blunt.

Fig. 19- shows a form of interlock for the parts of the ringlike device. 1

Referring now more particularly to the drawing, it will be observed that a ring embodying my invention is of multi-part character and preferably consists of two pieces. In the illustrated examples one of the pieces is of more than 180 extent and the other is complementary thereto, making a complete 369 ring. The pieces are preferably of the same width and of the same or approximately of the same thickness to resemble to be freely turnable without limit in a binding hole of the bound material. The larger piece may be resiliently expansible to receive between the juxtaposed edges thereof the smaller piece or insert. and thereafter contracts itself to embrace, the edges of the insert and thereby hold the-insert in place. Preferably there I is a tongue and-groove connectionat the places of engagement of the pieces and they may be assembled and disassembled by being resiliently snapped together and apart, by frictional sliding, or inany. other suitable manner. In accordance with one form of my invention the ends or jaws 29 of the part-annulus 21 are of generally knife edge form as at 22, and the cooperating margins of the insert 24 complement ally grooved as at 25 to snugly receive the edges The insert 24 may be formed of flat strip as shown and, because of its small extent circumferentially relative to the complemental part 21, will not materially detract from the general circular appearance nor will it offer any interference to'passage of the full circumference of the ring through a binding hole in the bound material.

In Fig. 1 several rings 21 are linked through a like number of elongated marginal holes 23 in a stack of leaves 29, the holes being of sufficient width to afiord clearance for the free movement of the rings therethrough as shown in Fig. 10,

while cooperating with the rings in holding the leaves with their edges substantially even, as when relatively rigid binding is employed. The holes are accordingly preferably of substantially the same length marginally as the rings to allow free turning of the links while preventing unevenness of the edges of the leaves. The ring, has the appearance in elevation seen in Fig. 2, wherein the ends 3| of the insert are flush with the bases 32 of the member 2|.

In Fig. 3, the binding rings 34 are relatively long, as are the binding holes 35 in the stack 35,

and accordingly fewer are used.

In Fig. 4 the binding ring 33 and hole 39 in the stack 40 extend throughout substantially the full length of the binding margin.

Fig. 7 shows how a stack of leaves with one loading may be inserted between the ends 20 of any part-annular member of the invention, such, for example, as the member 2A, with the binding hole arranged to receive either end 20. This figure also shows in dotted lines the member 2i linked through the hole.

Fig. 8 shows how' with this construction one or more sheets 42 may be readily added and removed, the gap in the member 2| being afterward filled by the insert 24.

Fig. 9 shows in dotted lines at IS the shape of the member 2| when unstressed and, in full lines, the shape when expanded to admit and resiliently clamp the insert 24 between the ends 20 of the member 2i.

Fig. 10 shows how the pencil 44 appearing in dotted lines also in Fig. 1 may be clamped between the binding means and the stack.

As will be seen in Fig. 11, the book may be open and lie substantially fiat.

Fig. 12 shows a modified insert 45 in which the groove at one or both ends may be rounded as at 46 to spread the ends of the insert 2| by a cam action to facilitate application of the insert.

In the form appearing in Fig. 13, the insert 48 differs from the insert 2A in that the insert 38 is concavo-convex in the direction of curvature of the member 2|.

The form of Fig. 14 differs from that of Fig. 13 in that the insert 51 is of substantially the same thickness as the ringlike member 5| and the latter has its end edges V-shaped as at 52 from both sides to fit in complemental grooves 53 in the insert.

In Figs. 15 and 16 the fiat insert 55 has its vshaped edges 56 shaped to fit the V-grooves 51 in the ends of the ringlike member 58.

In Fig. 17 the construction is like that of Figs. 15 and 16 except that the insert 60 has the same curvature as the ringlike member 6|.

Fig. 18 shows a structure similar to the first described form, differing therefrom only in that the end edges 53 of the ringlike member 64 cooperating with the insert 2d are not tapered.

Fig. 19 shows how any binder embodying my invention, may be formed to insure proper alinement of its parts. The ringlike part 68 may have a notch 69 receiving a lug 16 on the insert H, as also shown by way of example in Figs. 1, 2 and 12, although this construction may be reversed, as shown by way of example in Figs. 3 and 4, or otherwise modified.

Any of the various forms of inserts may bear indicia, as shown at 6! in Fig. l. The complemental split ring elements may be left plain so that they may be linked with the material to be bound irrespective of the indicia-bearing inserts to be assembled therewith.

I am aware that many changes may be made and details of construction varied through a wide range without departing from the principles of my invention, and I therefore do not purpose limiting the patent granted hereon otherwise than as necessitated by the appended claims,

which are to be interpreted as broadly as the' prior art will permit.
